Dr. Richard David Feinman, PhD

Richard David Feinman ("the other Feinman") is Professor of Cell Biology (Biochemistry) at the State University of New York (SUNY) Downstate Medical Center in Brooklyn, New York. Dr. Feinman’s original area of research was in protein chemistry and enzyme mechanism, particularly in blood coagulation and related processes.

Dr. Feinman has worked in several scientific areas including animal behavior and he has had a previous life in the visual arts. His friends consider him a Renaissance Man but he has made peace with the term dilettante.

His current interest is in nutrition and metabolism, specifically in the area of diet composition and energy balance. Work in this area is stimulated by, and continues to influence, his teaching in the Medical School where he has been a pioneer in incorporating nutrition into the biochemistry curriculum. Dr. Feinman is the founder and former co-Editor-In-Chief (2004-2009) of the journal, Nutrition&Metabolism. Dr. Feinman received his BA from the University of Rochester and he holds a PhD in chemistry from the University of Oregon.

Richard Feinman is principal author of the 26-author comprehensive review “Dietary carbohydrate restriction as the first approach in diabetes management: Critical review and evidence base.”

His recent book “The World Turned Upside Down - The Second Low Carbohydrate Revolution” describes how “How the science of carbohydrate restriction arising from a rag‑tagcollection of popular diets defeated the powerful low‑fat army and became the default approach to health.”

An Interview with Prof. Richard Feinman, PhD (Parts 1-3)

In early August I had the pleasure of being welcomed by Richard at his home in Brooklyn, NY. He was a most gracious host, and I felt privileged to enjoy a discussion with one of the technical leaders in the movement. Our conversation centred on something huge and inexorable that will stem the epidemic of 'diabesity' in our world; that's right folks - we were talking about the Second Low Carbohydrate Revolution.

It is finally upon us, riding on a tide of emerging science. And it is long, long overdue.

Low-carbohydrate nutrition and metabolismABSTRACT. The persistence of an epidemic of obesity and type 2 diabetes suggests that new nutritional strategies are needed if the epidemic is to be overcome. A

Analysis of dietary interventions. A simple payoff matrix for display of comparative dietary trials - Nutrition JournalObjective To provide a simple method for presentation of data in comparative dietary trials. Methods Individual data from each diet are ranked and all possible paired comparisons are made and displayed in a pay-off matrix which can be color-coded according to the magnitude of the differences between the two diets. Probability of outcome can be calculated from the fraction of matrix elements corresponding to specified conditions. The method has the advantage of emphasizing differences and providing the maximum amount of information. Results The method was tested with values from the literature and allows intuitive sense of the comparative effectiveness of the two diets. In a test case in which a cross-over study had been performed the matrix derived from theoretical paired comparisons (treating the data as two parallel studies) was consistent with the results from the actual pairing in the cross-over. Conclusion The matrix method is a simple way of providing access to the differences between dietary trials. It exaggerates differences but can be used in combination with group statistics that, conversely, provide reliability at the expense of detailed information.

Carbohydrate restriction improves the features of Metabolic Syndrome. Metabolic Syndrome may be defined by the response to carbohydrate restriction - Nutrition & MetabolismMetabolic Syndrome (MetS) represents a constellation of markers that indicates a predisposition to diabetes, cardiovascular disease and other pathologic states. The definition and treatment are a matter of current debate and there is not general agreement on a precise definition or, to some extent, whether the designation provides more information than the individual components. We consider here five indicators that are central to most definitions and we provide evidence from the literature that these are precisely the symptoms that respond to reduction in dietary carbohydrate (CHO). Carbohydrate restriction is one of several strategies for reducing body mass but even in the absence of weight loss or in comparison with low fat alternatives, CHO restriction is effective at ameliorating high fasting glucose and insulin, high plasma triglycerides (TAG), low HDL and high blood pressure. In addition, low fat, high CHO diets have long been known to raise TAG, lower HDL and, in the absence of weight loss, may worsen glycemic control. Thus, whereas there are numerous strategies for weight loss, a patient with high BMI and high TAG is likely to benefit most from a regimen that reduces CHO intake. Reviewing the literature, benefits of CHO restriction are seen in normal or overweight individuals, in normal patients who meet the criteria for MetS or in patients with frank diabetes. Moreover, in low fat studies that ameliorate LDL and total cholesterol, controls may do better on the symptoms of MetS. On this basis, we feel that MetS is a meaningful, useful phenomenon and may, in fact, be operationally defined as the set of markers that responds to CHO restriction. Insofar as this is an accurate characterization it is likely the result of the effect of dietary CHO on insulin metabolism. Glucose is the major insulin secretagogue and insulin resistance has been tied to the hyperinsulinemic state or the effect of such a state on lipid metabolism. The conclusion is probably not surprising but has not been explicitly stated before. The known effects of CHO-induced hypertriglyceridemia, the HDL-lowering effect of low fat, high CHO interventions and the obvious improvement in glucose and insulin from CHO restriction should have made this evident. In addition, recent studies suggest that a subset of MetS, the ratio of TAG/HDL, is a good marker for insulin resistance and risk of CVD, and this indicator is reliably reduced by CHO restriction and exacerbated by high CHO intake. Inability to make this connection in the past has probably been due to the fact that individual responses have been studied in isolation as well as to the emphasis of traditional therapeutic approaches on low fat rather than low CHO.We emphasize that MetS is not a disease but a collection of markers. Individual physicians must decide whether high LDL, or other risk factors are more important than the features of MetS in any individual case but if MetS is to be considered it should be recognized that reducing CHO will bring improvement. Response of symptoms to CHO restriction might thus provide a new experimental criterion for MetS in the face of on-going controversy about a useful definition. As a guide to future research, the idea that control of insulin metabolism by CHO intake is, to a first approximation, the underlying mechanism in MetS is a testable hypothesis.

Dietary carbohydrate restriction in type 2 diabetes mellitus and metabolic syndrome: time for a critical appraisal - Nutrition & MetabolismCurrent nutritional approaches to metabolic syndrome and type 2 diabetes generally rely on reductions in dietary fat. The success of such approaches has been limited and therapy more generally relies on pharmacology. The argument is made that a re-evaluation of the role of carbohydrate restriction, the historical and intuitive approach to the problem, may provide an alternative and possibly superior dietary strategy. The rationale is that carbohydrate restriction improves glycemic control and reduces insulin fluctuations which are primary targets. Experiments are summarized showing that carbohydrate-restricted diets are at least as effective for weight loss as low-fat diets and that substitution of fat for carbohydrate is generally beneficial for risk of cardiovascular disease. These beneficial effects of carbohydrate restriction do not require weight loss. Finally, the point is reiterated that carbohydrate restriction improves all of the features of metabolic syndrome.

Re-evaluating low-carbohydrate diets and mortalityIn the area of public health, there is little agreement on the dietary principles for the prevention and treatment of disease. Discussion is highly controversial; in particular for diets based on carbohydrate restriction. In their Article,1 Sara B Seidelmann and colleagues concluded that low-carbohydrate diets were associated with increased all-cause mortality. Here we re-evaluate their work from the standpoint of traditional and novel criteria, potential effect on public awareness, and the practice of nutritional medicine.
